Answer: Step 2
Step-by-step explanation:
The scale factor is defined as image/preimage, so since the image is circle F and the preimage is circle E, k should be equal to (radius of F)/(radius of E), or 1/2, not 2.
Use distributive property: multiply the number outside the bracket by each number inside it
1. 14x+21=35 14x=14 x=1
2. -32x-24=40 -32x=64 x= -2
3. 16-10x=-44 -10x=-60 x=6
Answer:
21 
in/hr
Step-by-step explanation:
Distance of snow fall = 3ft
Time taken = 1
hrs
Unknown:
Rate of snowfall = ?
Solution:
The rate of the snowfall is the same as the speed of the fall;
Rate of snowfall = 
Convert the ft to inches;
1ft = 12inches
3ft = 3 x 12 = 36inches
Input the parameters and solve;
Rate of snowfall = 
= 36 x = 21 in/hr
